UK-led study reveals hidden massive star clusters deep within nearby galaxies
Astronomers using the VLA and ALMA uncovered previously unseen giant star clusters embedded deep inside nearby galaxies. The findings show that young stellar activity drives the evolution of these galaxies, reshaping their interstellar environments. Multiple observations confirm the clusters act as hidden “ring factories” of star formation.

Transcatheter ViV a Solid Option for Failed Mitral Bioprostheses: SURViV
The SURViV randomized trial compared transcatheter mitral valve‑in‑valve (ViV) with redo surgical replacement in 150 patients with failed bioprosthetic mitral valves, many of whom had rheumatic disease. At one year, ViV showed a markedly lower all‑cause mortality (5.3% vs 20.8%) and fewer disabling strokes. Both groups improved symptoms and quality of life, but ViV patients experienced shorter hospital stays and fewer early complications. Surgical patients maintained better valve gradients, highlighting a trade‑off between early safety and long‑term hemodynamics.
